Heat power is an impartment performance index to choose the gear reducer. The working efficiency of the gear reducer lies on the value of the heat power when working with the temperature at which heat balance is achieved. Raising Heat power will benefit working efficiency, and reduce the waste of energy sources. The formula to calculate efficiency is deduced, and the heat power is tested by way of experiment. The heat radiating equipments with the structures of plank lumped and pipe ranked are developed. On the basis of this,the methods are brought forward to raise heat power of gear reducers considering the factors of designing, manufacturing and lubricating.
